RGT Roofing & Exteriors

Hanover requires a building permit for roof replacement, filed through the Building Department at Town Hall. Massachusetts code requires an ice-and-water shield membrane at the eaves extending at least 24 inches past the warm-wall line — important on the South Shore given combined snow and wind-driven rain — plus valley and penetration protection. On Hanover's 1960s-70s homes, tear-off can uncover soft sheathing at the eaves from past ice damming or tree-shaded moisture, and that deck repair is included in the permitted scope. Licensed contractors handle the filing and inspection.

Hanover sits in the South Shore cost band, near the eastern Massachusetts average. A standard asphalt tear-off and re-roof on a typical colonial, garrison, or raised ranch runs roughly $9,000-$18,000, with larger homes and steep multi-gable rooflines reaching $22,000. Switching from three-tab to architectural shingle adds modestly. Wind-rated detailing — sealed-down shingles and reinforced edge metal — adds some cost but can help insurability on the storm-exposed South Shore. Any deck repair found at tear-off is an add-on, and low-slope sections in EPDM rubber are quoted separately.

Massachusetts requires a written contract and a Home Improvement Contractor registration for most residential roofing work; ask for the registration number and check it before paying a deposit.
